CalcTape makes the arithmetic process visible - you can do multiple calculations and subsequently correct or change all numbers and operations. Made a mistake? No problem: Mark the wrong number in place via double-tap and correct it instantly. All results are being adjusted automatically!

CalcTape is a revolutionary new kind of pocket calculator. With CalcTape, also extensive calculations remain clearly structured:

- Input a long list of values to be calculated and never lose the overview - just like with an adding machine with a paper tape.

- Easily perform percent calculations for TAX and discounts.

- Copy the current result with a single tap for use in other Apps.

- If you should later change individual mathematical expressions, then the complete calculation is automatically updated.

- Input comments on single items and results and add notes wherever you want.

- You can use intermediate results to structure and to check your results.

The permission "Photos/Media/Files" is confusing. Google has combined permissions to groups recently.CalcTape requires only access to external storage (SD card) for saving its documents. The permission for accessing photos and media are not required or used.
